Input: add a new Novatek NVT-ts driver

2023-04-02T05:42:26+00:00

Add a new driver for the Novatek i2c touchscreen controller as found on the Acer Iconia One 7 B1-750 tablet. Unfortunately the touchscreen controller model-number is unknown. Even with the tablet opened up it is impossible to read the model-number. Android calls this a "NVT-ts" touchscreen, but that may apply to other Novatek controller models too. This appears to be the same controller as the one supported by https://github.com/advx9600/android/blob/master/touchscreen/NVTtouch_Android4.0/NVTtouch.c but unfortunately that does not give us a model-number either.

mfd: remove ucb1400 support

2023-02-01T16:23:38+00:00

The ucb1400 MFD driver and its gpio and touchscreen child drivers were only used on a few PXA machines that were unused for a while and are now removed. Removing these leaves the AC97 support as ALSA specific, no other drivers are now connected through this interface.

Input: add driver for Himax hx83112b touchscreen devices

2022-11-07T19:28:55+00:00

This patch adds support for Himax hx83112b touchscreen devices. As there are no publicly available data sheets for these devices, the implementation is based on the driver of the downstream Android kernel used in the Fairphone 3. This patch is a complete rewrite, though, and the code bears no resemblence to the original implementation. The driver has been tested on the aforementioned phone.

Input: Add driver for Cypress Generation 5 touchscreen

2022-11-01T14:57:33+00:00

This is the basic driver for the Cypress TrueTouch Gen5 touchscreen controllers. This driver supports only the I2C bus but it uses regmap so SPI support could be added later. The touchscreen can retrieve some defined zone that are handled as buttons (according to the hardware). That is why it handles button and multitouch events.

Input: add driver for Hynitron cstxxx touchscreens

2022-10-30T04:34:16+00:00

Add support for the Hynitron cst3xx controller found on devices such as the Anbernic RG353P and RG353V (the Hynitron CST340). This driver was built from sources provided by Hynitron to Anbernic (possibly via Rockchip as an intermediary) and marked as GPLv2 in the code. This driver was written strictly for the cst3xx series, but in most places was left somewhat generic so support could be easily added to other devices in the future.

Input: add Imagis touchscreen driver

2022-03-21T05:00:12+00:00

Add support for the IST3038C touchscreen IC from Imagis, based on downstream driver. The driver supports multi-touch (10 touch points) The IST3038C IC supports touch keys, but the support isn't added because the touch screen used for testing doesn't utilize touch keys. Looking at the downstream driver, it is possible to add support for other Imagis ICs of IST30**C series.

Input: goodix - add support for controllers without flash

2021-09-21T05:00:29+00:00

Some Goodix touchscreen controllers, such as for example the GT912, don't have flash-storage for their firmware. These models require the OS to load the firmware at runtime, as well as some other special handling. Add support for this to the goodix driver. This patch was developed and tested on a Glavey TM800A550L tablet. Note the "goodix,main-clk" and "firmware-name" device-properties used by the new code are *not* documented in the Documentation/devicetree/bindings/input/touchscreen/goodix.yaml device-tree bindings for now. Not documenting these is intentional. This is done because this code has only been tested on x86/ACPI so far, where devicetree is not used. Instead these properties are set through a software-fwnode attached to the device by the drivers/platform/x86/touchscreen_dmi.c code. This means that the use of this properties for now is purely a kernel-internal thing and the name/working of the properties may still be changed for now.
